Given numbers are 460,390,461,667,398
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 460,390,461,667,398 is 47728132140.
Find LCM of 460,390,461,667,398 with Prime Factorization
| 2 | 460, 390, 461, 667, 398 |
| 5 | 230, 195, 461, 667, 199 |
| 23 | 46, 39, 461, 667, 199 |
| 2, 39, 461, 29, 199 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 23 x 2 x 39 x 461 x 29 x 199 = 47728132140
Therefore, the lowest common multiple of 460,390,461,667,398 is 47728132140.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
460 x 390 x 461 x 667 x 398 = 21954940784400
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
461 : 1, 461
667 : 1, 23, 29, 667
398 : 1, 2, 199, 398
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 460,390,461,667,398, is 1.
Now, the common factors can be found like this.
460:2x 2x 5x 23
390:2x 3x 5x 13
461:461
667:23x 29
398:2x 199
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 5x 23 = 460
Therefore, the value for common factors is 460.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 21954940784400/(1x460)
LCM = 21954940784400/460
LCM = 47728132140
Thus, we can understand that the LCM of 460,390,461,667,398 is 47728132140.
